Onyx Auto Sales LLC

Mark is seriously the best car guy ever! Not only does he take his business seriously, but his morals and integrity are his #1 priority. He meticulously checks and drives every car on his lot, does the detailing himself to the highest quality, and is kind and generous. He goes above and beyond with his customers. He even went as far as helping me clean the seats in my own car that I’m selling after I purchased one from him, and he did it for free! I wouldn’t dream of buying a car from anyone else.

Had an amazing experience buying a used car for my wife here. Quick in and out and absolutely fantastic vehicle. We had shopped in slc that morning and a dealership that specialized in hail damages vehicles wanted more money for a pos than we paid here. Absolutely highly recommend!

Flawless Finish wants to give a huge shoutout to Onyx Auto Sales. Working alongside their team has been nothing but solid. The quality of vehicles they bring in and the pride they take in serving the community shows in every interaction. They care about doing business the right way, and that makes all the difference. From a detailing standpoint, you can tell they value presentation and long-term protection — not just moving inventory. That mindset aligns perfectly with what you stand for at Flawless Finish. If you’re looking for a dealership that stands behind what they offer and treats people with respect, Onyx Auto Sales is a place you can trust.

Mark is awesome! While we haven't bought a car yet from there (we still may) Mark answered MANY questions, and when we met in person he was kind and patient with all the questions. In addition, he is honest in his dealings which was a big deal to me. The car I looked at did have an issue when it was on autopilot (it was a Tesla) but given that they don't deal with many Teslas and Mark didn't experience it, totally understandable. Would I buy from Mark, yes, but it would have to be a car I liked of course!
